6 Claims.

The. invention contemplates the.provision of a,

devicewherein waste. heat of theengineis utilized, in. an exceptionally efficient and controlled manner, to heat the used oil prior. to itspassage in an upward direction through a body of filtering material.

Other objects and advantages will become apparent as the description of the invention proceeds with particular reference to the accompanying drawing, in which,

Figure l is a sectional elevation of the filter unit in accordance with the invention,

Figure 2 is a plan view of. a plate member forming part of. the .unit,

Figure 3 is a plan view of another plate. member forming part of the. unit, and

Figure 4 is a diagrammatic elevation of anoil level indicating means for use in association with the invention. Referring to the drawing, I is a container-comprising a cylindrical member 2 and the top and bottom closure members 3 and 4, acentrally extending rod 5.With nuts 6 and 1 serving to hold themembers in firmly assembled relation while permitting convenient access to the variouscomponent parts of the device.

Slightly spaced from the bottom is a fixed solid partition 8 forming a relatively small substan-.

tially closed heating chamber a at the base of the device. The. partition is inclined at an angle of about 10 to 15 with respect to the horizontal bottom member 4. The chamber 9 receives hot pombustion gases from the exhaust manifold it through pipe I! and discharges them through outlet l8. Means l9 are provided in outlet l8. for

spaced relation to the partition. Theperiphery of the plate H] is in engagement with the inner surface of the cylindrical member 2 but i preferably unattached thereto whereby it may be readily, removed from the container. The platelllforms an oil-preheatin chamber I2 extending between the plate and the. partition. Oil enters the. chamber 12, under normal oil pump pressure, through inlet 29, which is preferably located in the enlarged portion of thechamber.

Slightly spaced from the topofthe deviceis a second perforated circular-plate l3, which is also-inclined at an angle of about 10 to 25 with-- respect tothehorizontal bottom member l; The periphery of plate l3 is in engagement with the inner surface of the cylindrical member lbut is also preferably unattached thereto whereby the interior of the container isreadily accessible on. removal of the plate. Between the plates Wandvided on the plate to further assist in directing the oil flow into the tube. The other'endnof the tube is connected with aconduit 24' which leads the refined 011 back to the engine.

In operation, the contaminated oil enters the chamber l2, Where it is subjected to a substantially high temperature from the heating'chamber 9. This temperature is sufiicient to readily vaporize the gasoline and moisture which may be present in the oil. The inclined partition B-ensures a non-static condition of the oil and sediment in the chamber whereby localized overheating is avoided. The preheated oil rises through the perforations in plate I0 and passes upwardly through the body of filtering material I5, where, due to its preheated condition, itis substantially entirely freed from contaminating solid matter. As the reclaimed oil rises through the perforations in plate 13 it is directed into the tube 22 and thence back to the oil circulation system of the engine. An outlet 25-may-be provided in chamber 2| for the fumes and vapor.

If desired, means maybe provided for indicat-. ing any interruption in the normal flow of oil through the device. Such means may simply comprise a conduit 26 communicating with chamber 2| and with a transparent indicating tube 21 on the dash 28 of the vehicle in which the device is mounted. Thus, should for any reason the oil flow from the device be restricted or interrupted and the container become filled with oil, it will rise in conduit 26 and tube 21 to provide an indication of the interrupted flow.

Figure 4 illustrates another form of indicating means wherein the conduit 26 communicates with a chamberv 34 containing a float 29 having thereon, a contact plate 30 adapted, .on rising of the float, to engage contacts 3| and close the electrical circuit 32. In the circuit 32 is located any suitable alarm means, such as a signal, gauge, bell, or light 33. 7

It will be observed that the device described is of a simple, compact nature, and capable of inexpensive manufacture and convenient instalforated partition and top closure.

lation. The arrangement of the oil preheating chamber is such that a satisfactory and efiicient heating of the oil takes place while its location below the filter chamber results in a particularly effective filtering step.
